Xbox 360 already registerd!

Hi,
Bought a 360 today! Wooo (Wii60) Anyways i bought it pre-owned. I went to xbox 360 site to sign up and it says this console is already registerd! Sooo (noob-ish bit commin up) if i bought a 12 month xbox live thingy would this affect me to play online??

I bought a preowned 360 the other week, and it was fine. Just create a gamertag from the dashboard and select create silver live membership. This gave me a free month of Gold, after which I presume it will be easy enough to enter a code for Live.
